My guess, a player like PLD wanted out of the locker room, probably had other reasons too, city, management/coaching whatever. Usually it's not just one thing.
Yet there are likely destinations that would maybe fit ADA better too. Again I would expect a pittance of what he is worth on ice, yet given the NYR market they may find at least someone that wants out of wherever they are for similar yet opposite reasons. Business is business. If I were a GM who had a locker room which had some personality ADA similar types, then why not see if that could be a thing? GMs knowingly have kept/signed/traded for talent regardless, just like the Rangers did when they acquired ADA in the first place... among others.
